Because the molecules in the solid are tightly packed nd in gases they are not tightly packed...nd they have very space as they could contain any object in it....!!!!!!!!
Intermolecular attraction
Intermolecular forces
It is intermolecular force of attraction, it may be 1- dipole - dipole interaction, 2- vander waal's force of attraction.
Metallic bonding
In the interior the intermolecular forces of attraction is equal in all directions but the molecules at the surface of liquid experiences unequal intermolecular forces of attraction. the molecules at the surface are free so the adsorb liquid or gaseous molecules
The force of attraction is generally stronger in the molecules of a solid compared to a liquid. In a solid, the molecules are closely packed and have limited movement, allowing for stronger intermolecular forces to hold them together. In a liquid, the molecules have more freedom to move, resulting in weaker intermolecular forces.
Intermolecular attraction
Small covalent molecules have a weak force of attraction.
The intermolecular force of ClF is dipole-dipole interaction. This is because ClF is a polar molecule, with a significant difference in electronegativity between chlorine and fluorine causing a partial positive and partial negative charge, leading to attraction between the molecules.
Intermolecular forces
becaus they have high intermolecular force of attraction
It is intermolecular force of attraction, it may be 1- dipole - dipole interaction, 2- vander waal's force of attraction.
This is called an intermolecular force. It may be a van der Waals force, dipole-dipole attraction or a hydrogen bond.
Metallic bonding
In the interior the intermolecular forces of attraction is equal in all directions but the molecules at the surface of liquid experiences unequal intermolecular forces of attraction. the molecules at the surface are free so the adsorb liquid or gaseous molecules
Generally, the boiling point of a liquid increases if the intermolecular force, i.e. pressure, increases.
The intermolecular force in BF3 is London dispersion forces. This is because BF3 is a nonpolar molecule, so the only intermolecular force it experiences is the temporary weak attraction between temporary dipoles.
